ROOF.

SPECIFICATION forming part of Letters Patent N 0. 646,623, dated April3, 190Q. Application and April 29, 1898. Serial No.6'79,275. (No model.)

To all whom it may concern: 7

Be it known that LSAMUEL R. HAWTHORNE, acitizen of the United States,and a resident of Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in Roofs,of

which the following is a full, clear, and exact description, whereby anyone skilled in the View of a portion of a roof embodying my'improvement.through such roof. Fig. 3 is a detail view, on an enlarged scale,showing the hook and snow-guard. Fig. 4 is a detail front view of theguard.

In the accompanying drawings the letter adenotes the roof-boards,usually laid with their edges parallel with the lower edge of the roof,and the letter 6 denotes the slate laid on the roof in-the usual manner.A hook c has a bent. pointed end 0 driven into the roofboards and withthe body part of the hook underlying a slate, the hooked end 0 beingbent around the edge of the slate at the end and overlying its uppersurface. This hook is driven between two slates located in the lap belowthat in which the slate to be held is located, the hookedend of the hookengaging the edge of the slate which it holds about midway of its width.

A snow-guard d, preferably of angular form, is inserted underneath thehooked-end c of the hook c and is clamped between this hooked end andthe slate b. The foot cl of the snowguard extends some distance on eachside of the hook and prevents pressure of the hook on the slate at asingle point, which is apt to Fig. 2 is a detail view in section crackthe slate if from any cause the pressure of the hook thereon becomes toogreat. By in serting this snow-guard underneath the hook the pressure isdistributed over a considerable surface of the slate, and the upturnedportion (1 forms a snow and ice guard that prevents movement of a bodyof snow or ice along the roof.

A recess may be formed in the snow-guard for the engagement of the hookto afford means for securing the guard firmly in place, and this recessmaybe of any desirable form, as a groove d located lengthwise along thefront portion of the guard, or a hole d through the upturned portionnear the bottom thereof, or other equivalent means.

I claim as my invention- 1. In combination in a roof, a hook securedthereto and having a back-turned portion adapted to receive the edge ofa slate, and a snow-guard having a foot extending on opposite sides ofthe hook and interposed between the back-turned portion and the slateand an upturned portion located at an angle to the foot.

2. In combination in a roof, a hook secured thereto and having aback-turned portion adapted to receive the edge of a slate, a snow=guard interposed between the back-turned portion and the slate andhaving a foot extending on oppositesides of the hook, and'a recess inthe guard adapted to engage the hook.
